They don't but frankly no one who matters actually gives a s#it about HN anyhow.
HN is also much less representative of the demographics within the American tech industry now as well - almost all the references I see on here are stuff only men in their late 30s to 50s would recognize, and an increasing amount of users appear to be based in Western and Central Europe.
Heck, I'm on the younger end by HN standards (early/mid 30s) and when I introduced HN to my peers over a decade ago (this is my throwaway) even back then they complained that it was "toxic", "snooty", and "unhelpful". And it's reputation amongst the younger generation has only gotten worse.
HN has "SlashDot"ified, because most people are either in private groupchats on signal/imessage/discord or meeting each other with Luma invites.
